Small Reference Book for Knitting Bag?

I am a fairly new knitter. I have purchased many full-size knitting books of various types to learn from, but I’m now looking for a smaller reference book to keep in my knitting bag when away from home.

I have heard of several including the Vogue Quick Reference, The Knitter’s Companion by Vicki Square and the new The Knitter’s Handbook. Could anyone offer their more experienced opinion of which of these is the best to have? And would anyone know of any other smaller handbooks that offer a good range of knitting reference material to keep in one’s knitting bag when away from home?

Thanks.

Although I don’t own it, I hear that Vicki’s book is awesome.

Thanks for the advice.
